The pathway produces two five-carbon building blocks called isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAPP), which are used to make isoprenoids, a diverse class of … Therefore, the MVA pathway is likely an ancestral metabolic route in all the three domains of life, and hence, it was probably present in the last common ancestor of all organisms (the cenancestor). The major differences are the presence of fatty acid lateral chains bound by ester links to sn-glycerol-3-phosphate (G3P) in eukaryotes and bacteria, in contrast with archaeal membranes containing isoprenoid lateral chains and sn-glycerol-1-phosphate (G1P) bound by ether links. Most research in understanding regulation of IPP biosyn-thesis has been directed toward the mevalonate pathway in Bayesian phylogenetic tree of the HMGR. 2002; Matsuzaki et al. However, the respective function of each monomer is different from one class to the other, the two classes do not use exactly the same cofactors, and they are differently inhibited by statins. The mevalonate pathway is widely studied. Isopentenyl diphosphate is synthesized via mevalonate and nonmevalonate pathway [6, 7]. 2000). 2004). While most eukaryotes use the mevalonate pathway in their isoprenoid biosynthesis [112–114], Gram-negative bacteria (e.g., E. coli), some Gram-positive bacteria (e.g., Mycobacterium tuberculosis), Chlamydia, a few apicocomplexan protozoa (e.g., Plasmodium sp. The classical mevalonate pathway discovered in eukaryotes (left) and the new mevalonate pathway proposed in archaea (right) only share the first four steps (boxed area). To examine whether localized manipulation of the mevalonate pathway impacts innate immunity, we exploited a unique mucosal disease model, endometritis, where inflammation is a consequence of innate immunity. 2–4 and supplementary figs. The distribution of the isopentenyl isomerases IDI1 and IDI2 is much more complex. (B) Ancient transfer of the complete MVA pathway to a bacterial ancestor before the divergence of the contemporary bacterial phyla. This, together with the apparent nonhomologous biosynthesis of isoprenoids in archaea and bacteria, has led some authors to propose either that the cenancestor was acellular, namely, that it was not bounded by any type of membrane (Koga et al. 2001). 1 and supplementary fig. The mevalonate pathway, also known as the isoprenoid pathway or HMG-CoA reductase pathway is an essential metabolic pathway present in eukaryotes, archaea, and some bacteria. 6B). They identified an enzyme able to phosphorylate the isopentenyl phosphate into IPP (an isopentenyl phosphate kinase, IPK), and they proposed that it could be part of an alternative pathway to produce IPP in M. jannaschii in which the order of the phosphorylation and decarboxylation steps would be interchanged (fig. Some authors have proposed that the two nonhomologous pathways would have appeared twice independently, one in the bacterial lineage and the other one in the archaeal descent. Searches were run with 4 chains of 1,000,000 generations for which the first 250,000 generations were discarded as “burn in,” trees being sampled every 100 generations. In the next sections, we summarize the results of our phylogenetic analyses and propose an alternative view of the evolution of those pathways in the three domains of life. When information was available about functional sites important for the biochemical function of a particular enzyme, it was used in order to identify and remove likely nonorthologous enzymes or enzymes unable to catalyze a given reaction. Synthesis of Heterologous Mevalonic Acid Pathway Enzymes in Clostridium ljungdahlii for the Conversion of Fructose and of Syngas to Mevalonate and Isoprene Appl Environ Microbiol . "The discovery of a mevalonate-independent pathway for isoprenoid biosynthesis in bacteria, algae and higher plants." 2004; Grochowski et al. Rohmer99: Rohmer M (1999). The MEP pathway, capable of generating IPP and DMAPP from D-glyceraldehyde-3-phosphate (G3P) and pyruvate, was discovered in the 1990s in bacteria and plants (Rodríguez-Concepción and Boronat 2002; Phillips et al. 2000; Martin and Russell 2003), the absence of lipid membranes in the cenancestor. BI trees were reconstructed using the program MrBayes v. 3.0b4 (Ronquist and Huelsenbeck 2003) with a mixed substitution model and a Γ distribution of substitution rates with four categories. 60 0 obj The complete sequence data set for each enzyme of the MVA pathway was first analyzed by Neighbor-Joining (Saitou and Nei 1987) using the MUST package (Philippe 1993) to obtain preliminary phylogenetic trees in order to select some representative sequences with which to carry out more detailed maximum likelihood (ML) and Bayesian inference (BI) phylogenetic analyses. Also known as the reductive acetyl-coenzyme A pathway. 61 0 obj The most recently discovered example, called the “archaeal” mevalonate pathway, is a modified version of the canonical eukaryotic mevalonate pathway … Bayesian phylogenetic tree of the HMGS. 3), which was interpreted as a complex history of HGTs and specialization leading these sequences to be present in several MVA pathway–lacking organisms (Gophna et al. Our work supports that each route is ancestral to one of the domains, but it is not enough to decide whether these pathways were present in the cenancestor or not. Oxford University Press is a department of the University of Oxford. 2004). 52 0 obj 2 E). Mevalonate is produced by a membrane-bound enzyme of the endoplasmic reticulum, 3 ... pathway that includes HMG-CoA reductase; and uptake from exogenous lipoproteins by means of the cell surface receptor for plasma LDL (Brown and Goldstein, 1980). <> (2004). However, a few bacteria (including some Gram-positive), fungi, and animals (including humans) synthesize their isoprenoid precursors using mevalonate pathway whereas others possess the two full pathways . Mevalonate diphosphate decarboxylase (MDD; EC 4.1.1.33) catalyzes the irreversible decarboxylation of mevalonate diphosphate in the mevalonate pathway to form isopentenyl diphosphate, which is a precursor in the biosynthesis of many essential polyisoprenoid natural products, including sterols. 2000; Kuzuyama 2002). All these eukaryotic groups carry plastids (either photosynthetic or, in the case of apicomplexa, highly derived), suggesting that they obtained the MEP pathway through the transfer of genes from the original cyanobacterial endosymbiont that originated the plastids (Lange et al. 6A), an idea that has already been advanced and used by some authors as an argument to discard the presence of lipid membranes in the cenancestor (Martin and Russell 2003). The characterization of the missing archaeal phosphomevalonate decarboxylase, including its distribution and phylogeny, will be a major help to understand the differentiation of those three pathways in the tree of life. According to this scenario, the last common ancestor of all organisms (the cenancestor) would have had no isoprenoids (Lange et al. The mevalonate pathway, also known as the isoprenoid pathway or HMG-CoA reductase pathway is an essential metabolic pathway present in eukaryotes, archaea, and some bacteria. As mentioned above, the MVA pathway, described for the first time in eukaryotes, has traditionally been considered as the main way to produce IPP and DMAPP in eukaryotes and archaea, whereas the MEP pathway has been affiliated to bacteria- and plastid-bearing eukaryotes (Lange et al. 2008; Moustafa et al. If we exclude the extremely improbable possibility that the pathway was assembled in the three domains by independent recruitment of homologous enzymes carrying out other functions, three other possibilities concerning this question can be proposed. This enzyme was recently discovered from haloarchaea and certain Chroloflexi bacteria, but their enzymes are close homologs of diphosphomevalonate decarboxylase, which are absent in most archaea. Production of isopentenyl diphosphate from mevalonic acid requires three consecutive ATP‐dependent reactions, the last of which is catalyzed by mevalonate diphosphate decarboxylase (MDD; EC 4.1.1.33).

Essential metabolic pathway present in eukaryotes, archaea, and some bacteria. For convenience, the classical bacterial rooting of the tree of life has been adopted. The MVA pathway is also found in a few bacteria, what has been explained in previous works by recent acquisition by horizontal gene transfer (HGT) from eukaryotic or archaeal donors. The classical mevalonate pathway is found in most eukaryotes, including humans; statin drugs are used to inhibit this pathway to treat those with high cholesterol and reduce the risk of heart disease. 4), also yielded phylogenetic trees with a good global agreement with the accepted phylogeny of organisms. 56 0 obj This pathway, therefore, might consume less energy than other mevalonate pathways to produce precursors for isoprenoids. <>stream Second, plants, other photosynthetic eukaryotes, and apicomplexa (a clade of parasitic protists derived from a photosynthetic ancestor) have been found to contain the MEP pathway in addition to the MVA one. The second pathway does not use the compound mevalonate and is found in many, but not all, bacteria as well as the chloroplasts of plants. They fulfill diverse biochemical functions as major structural membrane components in archaea, photosynthetic pigments, hormones, quinones acting in electron transport chains, and plant defense compounds (McGarvey and Croteau 1995; Lange et al. Mevalonate Pathway The mevalonate pathway, also known as the isoprenoid pathway or HMG-CoA reductase pathway is an essential metabolic pathway present in eukaryotes, archaea, and some bacteria. Flask scale fermentation was carried out to confirm that mevalonate was produced when the atoB, mvaS, and mvaE genes (upper mevalonate pathway) were preferentially expressed. All these molecules are oligomers synthesized by organisms of the three domains of life through successive condensations of two activated forms of isoprene: the isopentenyl pyrophosphate (IPP) and the dimethylallyl diphosphate (DMAPP) (Ruzicka 1953). is recipient of a PhD fellowship of the French Research Ministry. Mevalonate pathway, also known as HMG-CoA reductase pathway or the isoprenoid pathway, is an important metabolic pathway essential in eukaryotes, archaea, and some bacteria. In the 1960s, Bloch and Lynen identiˆed the mevalonate pathway for cholesterol biosynthesis.4,5) In this pathway, three molecules of acetyl-CoA condense successively to form 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) (Fig. Bacterial class II HMGR. Mevalonate Fermentation. mevalonate-dependent isoprenoid pathway from S. cerevisiae into operons and expressed them in E. coli.To simplify the task of engi-neering an eight-gene biosynthetic pathway,we divided the genes into two operons, referred to as ‘top’and ‘bottom.’The ‘top’operon, MevT, transforms the ubiquitous precursor acetyl-CoA to (R)-mevalonate "Isolation and characterization of a cDNA encoding Arabidopsis thaliana mevalonate kinase by genetic complementation in yeast." This has implications on the classical bipartite vision of the distribution of isoprenoid biosynthesis pathways in the three domains of life. 2000). 2004; Dutoit et al. Our results, supporting the possibility of an ancestral MVA pathway, provide an additional argument for the hypothesis that all the major components of contemporary membranes (phospholipids composed of glycerol-phosphate bound to lateral chains of fatty acids and/or isoprenoids) existed in the cenancestor and that the specialization observed in current cellular membranes is most likely secondary and linked to the divergence of the three domains of life. The case of the HMGR will be discussed below, but we can highlight the existence of two different classes of enzymes, one present in some Proteobacteria and Actinobacteria and the other widespread in the six MVA pathway–bearing bacterial phyla. the mevalonate pathway is used in all eukaryotic organisms to synthesize iPP, the central precursor of isoprenoids. 2009). Bacteroidetes, most actinobacteria, and some proteobacterial species have IDI1, whereas Firmicutes, Cyanobacteria, Chlorobi, Chloroflexi, Deinococcus–Thermus, Spirochetes, Deltaproteobacteria, and some other proteobacterial and actinobacterial species contain IDI2 (supplementary figs. In contrast, the class Sulfolobales (Crenarchaeota) contains both PMK and MDC homologues branching with a strong support in an intermediate position between the eukaryotic and the bacterial sequences (table 1, supplementary figs. Actually, despite several sporadic cases of HGT, three ways to produce IPP and DMAPP would exist, each of which is widespread within a domain of life: the MEP pathway in bacteria, the classical MVA pathway in eukaryotes, and the alternative MVA pathway in archaea (fig. <>stream Today, the MVA pathway is considered to be the major route of IPP and DMAPP synthesis in eukaryotes and archaea (Kuzuyama 2002; Boucher et al. 58 0 obj 6, Supplementary Material online). The classical mevalonate pathway or HMG-CoA reductase pathway is a metabolic pathway from the biosynthesis of isoprenoid precursors present in most higher eukaryotes and some bacteria. Two distinct routes of IPP biosynthesis occur in nature: the mevalonate pathway and the recently discovered deoxyxylulose 5-phosphate (DXP) pathway. PMID: 10584331 MetaCyc Pathway: mevalonate pathway I (eukaryotes and bacteria) Enzyme View: Detail Level: This view shows enzymes only for those organisms listed below, in the list of taxa known to possess the pathway. The isoprenoid side chains are formed from mevalonate (13). Nat Prod Rep 16(5);565-74. 5C). 3) and MVK (fig. While the majority of bacteria utilize a single pathway for isoprenoid biosynthesis, Listeria monocytogenes is unusual in possessing the complete set of genes for both pathways. The mevalonate concentration in culture broth of E. coli harboring both the whole mevalonate pathway and the β-carotene synthesis pathway reflects the difference between production and consumption of mevalonate through the top MVA pathway and the β-carotene synthesis pathway, respectively. 2009-01-12T16:15:11Z (2004) also showed that the dehydrogenases involved in the synthesis of G1P and G3P in archaea and bacteria evolved from universally spread enzymatic families that were most likely present in the cenancestor. Some bacteria, however, are known to possess the mevalonate pathway genes. PMID: 7958957. Stabilization of the chain parameters was verified using the program TRACER (Rambaut and Drummond 2003). 2004), whereas the MEP pathway would be characteristic of bacteria (Lange et al. �OJVO'�R�^ �D����Y{��d�t��2���4�Uy�}�Pl(�yv:}�bo��&��8�f�Ȋޒ�$k�N���o�(M2���� �����S7wM��(��I4VE+Zt�؊�tLp��|�}���\�1O�!�ᐁg���n�J�(v-L(�� However, IDI genes are present in the genomes of a variety of bacteria, probably because they may allow these organisms to isomerize IPP and DMAPP according to their metabolic requirements at a given moment. ML tree reconstructions were done with the program TREEFINDER (Jobb et al. 2004) and some bacteria, notably some Firmicutes, do possess the genes of the MVA pathway (Boucher and Doolittle 2000; Wilding et al. <>/Font<>/ProcSet[/PDF/Text]>>/Rotate 0/TrimBox[9 9 594 792]/Type/Page>> 2001, 2002). 6C). The last three enzymes of the classical MVA pathway, PMK, MDC, and IDI 1 (IDI1), did not follow this “three domain” distribution because they are absent from most archaeal species, as noticed in previous works (Smit and Mushegian 2000; Boucher et al. Share. Unité d'Ecologie, Systématique et Evolution, Centre National de la Recherche Scientifique, Université Paris-Sud, Orsay, France. Topics similar to or like Mevalonate pathway. The possibility of an isoprenoid biosynthesis pathway operating in the cenancestor has interesting implications on the open question about the presence and nature of the membrane of this ancestral organism. The first one would entail that an ancient bacterial lineage obtained all the enzymes by HGT from another domain of life, archaea or eukaryotes, followed by a period of fast evolution that would be responsible of the high divergence of the bacterial enzymes from the original ones. This pathway, called methyl-D-erythritol phosphate (MEP) or non-mevalonate pathway, is responsible for biosynthesis of isoprenoids — molecules required for cell survival in most pathogenic bacteria. These results are consistent with the existence of a modified MVA pathway in archaea (Grochowski et al. In cases where a particular enzyme was missing in KEGG for one domain, we used sequences from the other domains as queries. The metabolic profiles of ELPP000 and ELPP010 strains are illustrated in Fig. The lab targeted the IspH enzyme, an essential enzyme in isoprenoid biosynthesis, as a way to block this pathway and kill the microbes. The other two possibilities would imply that the MVA pathway was ancestral to bacteria, which would be the consequence either of the acquisition by an ancestral bacterium of the pathway from another domain before the radiation of different bacterial phyla (fig. Wood–Ljungdahl pathway. <> Mevalonate, a ubiquitous biosynthetic intermediate of isoprenoids, is utilized as a moisturizer in cosmetics and a chemical in biochemical research. This pathway, called methyl-D-erythritol phosphate (MEP) or non-mevalonate pathway, is responsible for biosynthesis of isoprenoids – molecules required for cell survival in most disease-causing bacteria. This tree was reconstructed using 84 representative sequences and 232 conserved sites. 2006).

The mevalonate pathway, also known as the isoprenoid pathway or HMG-CoA reductase pathway is an essential metabolic pathway present in eukaryotes, archaea, and some bacteria. This suggests that the alternative pathway, including the recently characterized enzymes IPK and IDI2, was ancestral to archaea.

It is not surprising that some of the enzymes involved in isoprenoids biosynthesis could be targets for the development of novel antibacterial agents. All rights reserved. This implies that each domain of life possesses a characteristic major isoprenoid biosynthesis pathway: the classical MVA pathway in eukaryotes, a modified MVA pathway in archaea, and the MEP pathway in bacteria. 5A). 1). 2004; Grochowski et al. 1999; Wilding et al. uuid:d32bbece-1dd1-11b2-0a00-380000000000 On the one hand, our results confirm the conservation in archaea of an MVA pathway partially different from eukaryotes. While mammals all use the mevalonate pathway , bacteria usually carry genes for only one of the two pathways . Moreover, MEV strongly reduced T cell activation, thus revealing the importance of endogenous eukaryotic ligands (Fig. As isoprenoids are essential components of the archaeal membranes, their late emergence might imply, in the opinion of some of these authors (Lange et al. The different glycerol stereoisomers would have been selected afterward in the different lineages. uuid:d32bbecb-1dd1-11b2-0a00-050927edca00 Available from: Elucidation of the methylerythritol phosphate pathway for isoprenoid biosynthesis in bacteria and plastids. endobj metabolic pathways exist for involved in isoprene synthesis. J.L. Our results complete the data about the existence of an alternative MVA pathway in archaea as proposed by some authors (Boucher et al. In the light of our results, a more parsimonious third hypothesis emerges: the classical MVA pathway would have been present in the cenancestor and inherited not only by archaea and eukaryotes but also by bacteria, which would have replaced it by the MEP pathway in a variety of bacterial phyla (fig. 2006; Dutoit et al. This pathway is widely known being involved in cardiovascular diseases. Biochemical studies of HMGR showed that both classes share similar active sites and form homodimers. In particular, this includes the emergence of the bacterial sequences as a monophyletic group distinct from archaea and eukaryotes (i.e., the three domains topology). 2004). While the mevalonate pathway has previously been reported to be essential, here we demonstrate that the nonmevalonate pathway can support growth of strains 10403S and EGD-e, but only anaerobically. The distribution of the different isoprenoid biosynthesis pathways in the three domains of life is very complex but displays a clear preferential relationship: the MEP pathway in bacteria, the classical MVA pathway in eukaryotes, and the alternative MVA pathway in archaea. The lab targeted the IspH enzyme, an essential enzyme in isoprenoid biosynthesis, as a way to block this pathway and kill the microbes. Isoprenoids constitute one of the largest families of biological compounds, encompassing around 30,000 known products in the three domains of life (bacteria, archaea, and eukaryotes).
